With a bespoke remap the Mazda 3 2.0 CiTD 143bhp gains +27 bhp and +50 Nm, rising from 143 bhp / 360 Nm to 170 bhp / 410 Nm (19% more power).

Who is this remap for?
On a diesel, the bigger gain is usually in torque. Expect stronger pulling from low revs, easier overtaking and a more relaxed drive on the motorway. 143 → 170 bhp equals roughly 107 → 127 kW.
Figures are guide values from our rolling road and comparable vehicles. Results depend on the vehicle's condition, hardware and fuel quality. Remapping in the UK: let your insurer know about the modification. DPF, EGR and AdBlue solutions are supplied for off-road and motorsport use only and are not legal for use on UK roads.
